Ascending multi-stage distillation apparatus and method utilizing a feed-liquid-lift system
Abstract
Abstract A MULTI-STAGE DISTILLATION SYSTEM, PARTICULARLY USEFUL FOR DESALINATION OF SEA WATER, IS DESCRIBED COMPRISING A PLURALITY OF EVAPORATORS AND CONDENSERS DISPOSED AT ELEVATIONS INCREASING FROMTHE FIRST STAGE OF HIGHEST TEMPERATURE AND PRESSURE TO THE LAST STAGE OF LOWEST TEMPERATURE AND PRESSURE, THE FEED LIQUID BEING MOVED UPWARDLY AGAINST GRAVITY THROUGH THE EVAPORATORS BY THE ENERGY OF VAPORIZATION AND DIFFERENCE IN PRESSURE BETWEEN STAGES, AND THE COOLING LIQUID MOVING DOWNWARDLY BY GRAVITY THROUGH THE CONDENSERS AGAINST INCREASING PRESSURE. A FEED-LIQUID-LIFT SYSTEM IS DESCRIBED INCLUDING A DOWNFLOWING LIQUID COLUMN OF THE FEED LIQUID CONTINUOUSLY DRIVING A LONGER UP-FLOWING BOILING-MIXTURE COLUMN OF THE FEED LIQUID MIXED WITH VAPOR, WHILE LIQUID AT THE LOWER AND OF THE UP-FLOWING BOILING-MIXTURE COLUMN CONTINUOUSLY EFFECT A HYDRAULIC SEAL BETWEEN ADJACENT STAGES.
